Enabled automated doc building. Changes:
-build.xml, phing build file
-@package tags at acl_selector.php and db_update.php
-added documentation and some IDE files to .gitignore
-automated tool to find files that corrupt the doc build process
-removed ansi characters from SSH1.php, docBlox could not handle them

This script assumes there is a file or set of files + * breaking the build when it is included in that list. It tries to calculate the smallest list containing these files. + * Unfortunatly, the original problem is NP-complete, so what the script does is a best guess only. + * + * So it starts with a list of all files in the project. + * If that list can't be build, it cuts it in two parts and tries both parts independently.

Maybe the smallest set consists of two files and both of them were in different parts when + * the list was divided, but by now it is my best guess. To make this assumption better, the list is shuffled after every step. + * + * After that, the script tries to remove a file from the list.
